ABSTRACT:
A liquid dispenser according to the present invention comprises a container having a rigid top portion and an elastic bag portion, an actuator having a cylindrical portion engageable with the top portion of the container, a pair of flexible legs each having a bent portion and a valve aperture, and a valve device having a valve stem extending longitudinally in the container. The valve stem is engaged with the flexible legs at their ends. A spring is mounted between the actuator and the valve device for biasing the valve device to a closed portion. When pressure is applied manually onto a predetermined portion of the container, the flexible legs are actuated to move the valve out of its closed position so that a liquid in the container is discharged through the opened valve aperture.
